Abstract Cr-Mo low alloy steel has important applications in industrial production. CCT curve is an important basis for the research on the phase transformation of supercooled austenite. The deformation and cooling process were simulated by Gleeble-3500 thermal simulation tester and DIL 805 dilatometer in this paper. The superelement model was used to do the thermodynamic calculation and analysis. The results indicate that the deformation has a great influence on the phase transition free energy of Cr-Mo low alloy steel during the process of transformation， also on activity of carbon， mole fraction of carbon on phase boundaries， driving force of transformation and driving force of nucleation， which has an effect on the the incubation period and the degree of supercooling of the transition in the end. The measured results show that the incubation period and the degree of supercooling consistent with the theoretical calculated results. The deformation can also be used to enhance the critical cooling rate ferrite transformation. The finest ferrite grain can be obtained when the cooling rate is 0.3 ℃/s. Therefore， appropriate deformation and cooling process is of great importance in improving the microstructure and properties of Cr-Mo low alloy steel.
